An adjustable arm 25 extends fromthe upper end of upper templet A andonthe freeend'thereof is anchored a right angled flange 2 3. Slidablyseated in a recess on one leg of this flange is a countersunk plate 24that is flush with the face of that leg of the flange in which it isseated. Then the gauge is used in con unction with door frames H,

arm. Extending through athreaded opening in the lug is an adjustmentscrew 27.

Spaced frointhe adjusting'fs'crew is bolt 31 that is slidable in anopeningin-tlie lug 26. One end of a bowed plate-spring 30 is secured tothe lug 26 and the other end en gages the head o'f bolt '31 for normallyurging the bolt upwardly. On the outer end of bolt islarflat bar 29 thatclamps over the lower corner of a door when the bolt iser- I tended asshown in Fig. 2. l/llhenthegauge ,is not used ona door, the bar willseat in a pocket in the lower face of lug-26 when bolt.

31 is turned in a manner similar to the other clamps to be presentlydescribed. The inner ends of arms 25%25" are e l dtothejouter ends ofthe templet bars 40, ll of templets C and Ain the same mannerthat thetongues are secured thereto.

Adjacent each templet A, B and C, are

gripping members indicated generally at 32,

pled with the templets and are adapted to swing toa posit on at rlghtangles to the .bodyof the'gaugeand engage the one side' face of a door Hat spaced intervals.

-Slnce each of the "rippingmembers is formed in thesame manner, it isbelieved that the-following description directed'to one of thep'rlppmgmembers Wlll give a clear understandingiofthe others. Eachgripping member'consists of abolt 35 pivoted at one "end to anupstanding lug 36 that threadably engages I with the respective arms andtongues. This lug 36 as shown is detach-ably secured to arms 25. and '25for the upper. and

lower gripping members, whereas the lug 36 for the middle grippingmember is anchored'to slitted tongue 18.

' The inner faces-"of one angle" bar 40 for:

each templet, are graduated in inches'and fractions of inches as at 42and the graduationscontinue over the upper edge of the vertical leg ofeach bar. Adjacent each end, the angle bars on the same side of eachtemplet, support'a pair of clamps 44 formed on the ends of sliding androtatable bolts similar in all respects to the bolt 31 heretofore de- V"b-d. lug 26 that is ad acent the lower end of the fell 0 These clamps44, when not in use, are seat-- ed in recesseslh in the outer face ofthe vertical legs of the angle bars to which they are attached. Inextended relation, these clamps hold the body of the gauge flush withthe adjacent. one end and a movable abutment plate 47 adjacent the otherend. These abut- .mont plates are right angled in cross section ,withthe anglesthei'eof oppositely directed.

Moreover. these abutment plates are disposed.

transversely of and rest in confronting angles oftho bars 40 and 4:1.The vertical legs ell-1m abutment plates define the area of the recesstabs routed for thehinges The horizontal legs of the fixedabutmentplates are secured tothe horizontal legs of the side bars of thetemplets by screws 48. l The horizontal legs ,of the movable abutmentplates 47 are secured to the inner ends of slotted plates 49 that slideinthe space between the side angle bars under the respective slittedtongues 15, 16

one face'of the door opposed to the face engaged by thegripping-members.V

Each templet has a fixed abutment plate 16 and 17. The slidingpla tes4:9 are locked in] any position by means of a thumb screw 50.

To the bottom of the motor-driven router R is secured a plate 51 that isflat. In the center the plate is formed with an opening to permit therouting tool T to extend therethrough and fronrthe central opening thebottom .face of the plate is formed with a groove that extends inopposite directions to the outer ends of the plate.

ations 54 which cooperate with'an arrow 55 formed on theoutwardly'disposed leg56 of the guide member in any position with respect to the groove. The guide member 53 is a fiat bar that dependsbelow the plate 51v and abuts against the vertical leg of the side anglebars 40, ll depending upon which side ofthe plate 51 the guide isdisposed.

It will be undors ood that the guide 53 is adapted to be positioned oneither side of the routing tool. Thus-it will be seen that the distancefrom the routing tool to the guide 53 will determine the width of thehinge seat, while the distance between abut-' ment 46, and lTwilldetermine the length of the hinge seat to 'berouted out ofthe edge of rthe'door H. e i

In the application of the invent-ion, the

templets A, B and C are adjusted to approii'imate positions of thehinges on the frame H. Plate 24: is moved into its recess on flange 2-3and the body off'the gauge is disposed against the side of the framescrew,-

.,. ing down on bolt 27 until plate 28 abuts the floor. Then the bridgepole P is placed across the frame with one end engaged with theotherside of frame H and the other end abutting the body of thegaugeintermediate the ends. This bridge pole is formed ofa pair of rods59 and 62. The one section 59 is formed with a socket 61 in one end, inwhich is seated a coil. spring that bears against the inner end of rod62 that telescopically fits into the socket. 4 end of section 62 andextendsthrough a slot (i l in the wall of socket 61 to limit the movcment of the rods with respect to. eachother.

Having positioned the gauge on the frame H, movable abutment plate 4.7on each templet A, B and. C, is adjusted to the length.

oi the, hinge seat to be routed. Next, the guide plate '53 on the routerR is set to the width oi the hinge. Then the router is applied to eachtemplelis A, l? and U within thelimits of abutment plates 46, l? and tosuch a width until the guide plate 53 abuts the upstanding leg of theside angle bar. With the same adjustment, the body oi. the gauge is thentransferred to the doorand the hinge seats on the door are cut with oneand the same setting, insuring matching of the hinges.

It will be understood that a mortise for a door lock and its keeper maybe made by:

A pin 63 is'anchored in the anjappli *ation of the central templetBin'the thesame manner as described for hinge seats.
